1. GEOGRAPHICAL INFORMATION SYSTEM (GIS)
APPLICATION OF
GEOGRAPHICAL INFORMATION SYSTEM (GIS)
IN WATER INDUSTRY
DR NOORDIN AHMAD
GIS . REMOTE SENSING . GPS . DIGITAL MAPPING . SURVEYING

2. CURRENT STANDINGS ( general issues)
Paper based information
Disintegration of information (drawings and textual are not together)
No uniform standards for the capturing data
No standardized software
Long turnaround time to capture and maintain CAD-based
Non proper definition and procedures for attributes input
No proper updating of information
Planning and maintenance not based on proper analysis

3. OBJECTIVES OF GIS
1. Makes information more accessible (digital environment)
2. Identify spatial (locational) based assets
3. Improve Customer service
4. Integrated data management and decision support system

4. POSSIBLE SOLUTION WITH GIS
Digital information
Integration of information (Pipeline, Assets, billing, etc )
Standards procedures for the capturing data
Short turnaround time to update information
Easier and consistent updating of information
Planning and maintenance is based on proper analysis

The future pipeline network
Som vi kender det fra UR-planen i DK mn mere simpelt (for der ligger nok ikke meget planlægning om udvidelser mv som vi kan bruge).
Men vi laver med AQUIS nogle beregninger og prioritere sammen med vandforsyningen nogle år frem. Planen vi lkunne ses som temaplot med år for renovering (øverst). Vi sætter et lille budget op (næste billede). Endelig iddeler vi ledningerne i kategorier (billede 3). Sidst indsætter vi informationer om fremtidsplaner for alle ledningerne i ledningsregistreringen (den røde ring).

17. Call Centre: Locating Consumer
The red highlight indicated the location of the water meter
of the caller. The attribute shows that the water meter is
linked to the consumer info table, enable a quick query on
consumer location to be carried out.
Finding caller by name or Acc No.
CAD data model – scant information about attributes
Coverage data model – georelational
spatial data in indexed binary files
Limitation: features are aggregated into homogeneous collections of points, lines and polygons with generic behaviour. The behaviour of a line representing a road is identical to the behaviour of a line representing a stream.
Sustainable model – meaning not only for today’s application, but will cater for the application in future, and it’s extensible.
Without OO model, have to write external code loosely coupled to features and prone to complexity and error.
